Autolite Iridium XP Automotive Replacement Spark Plugs, XP6203 (4 Pack)

These worked great for my car. Swapped out the old plugs and the engine started running smoother right away. Acceleration feels better and the idle is nice and steady now. Super easy install and they seem really well made. For the price it's a no brainer if you want to do some quick maintenance yourself. I'd definitely buy them again next time I need a tune up.

Spark plugs bought for 2013 Kia Soul. Parts fit and have had no issues for months. Great price for them. The same brand was triple the price at O'Reillys

Great set of spark plugs

Good price

Fit my 2013 Hyundai Sonata 2.4L and seem to be working well. I noticed more power and quieter acceleration with these.

Put these in to replace some old spark plugs in a 2015 Optima that had 85k miles. Works with no issues.. my gas mileage seems to be slightly better though I may need to drive a little more to determine that. My engine seems to be a bit quieter when accelerating as well. Haven't noticed much difference in acceleration or anything like that. Smooth idle as well. Nothing else really to say

My car eats a set of spark plugs every 30k miles. I’ve tried all the expensive brands hoping to find some that last longer, these seems to perform just as well and last just as long as those top tier brands.
